Welcome! My goal is to do my very best to understand your situation and to provide a full and complete answer for you.
Good morning. You will file Articles of Dissolution with the NH Secretary of State. You can obtain, complete, and file this form online at their website: http://www.sos.nh.gov/corporate/Corpforms.html
Then, with the IRS, it depends upon the activities of your NH corporation
....i.e, employees? retirement plan? etc., etc. You can find a complete checklist at http://www.irs.gov/Businesses
